Application filed January 17, 1911. Serial No. 603,130.

To 141/ i l/1.0m it WLIIII/ (mu-rm Be it known that it, in'riiifu PHIL,a eiiixen of the United States, residing in the borough of ivlnnhatt'anof the city of New fork, in the State of New York, have invented certainnew and useful improvemerits in Hutiler Cub-Guts, of \vhieh thefollouing is a speeifieution.

The objectof this invention to provide nieuns arranged in the. exhaustpipe oi an engine, such as a gas or hydrocarbon engine. whereby theexhaust gases may he. direetwt or exhausted without passing through theIlltlllltl'.

The invention (insists in the new and novel features o1" eonstrinaionand cone hinations of pa 'ts hereinafter set forth and claimed andrelates particularly to improvements on the construction set forth andclaimed in my application for Letters Peteni: filed April 13, lJlO,Seriui To. 5

In the accompanying tll't1\\llgb.'* l is a plan riew partly in sectionof my littprovcd niulller cut out. 2 represents a side elevation. insection.

The cutout 1 may he urrauge huust pipe between the pipe se nected to theengine and the section 33 connected to the mutiter. The euti'iut" is socured by its respective ends t and 5 to the sections 2 and 3respectively by any suitable means as the flanges 6 secured in place bysuitable bolts 7.

The cutout comprises a centre-.1 or drum portion 8 and a. cutout bypasst which may he formed of a sepnratipieee seeu ed thereto by means 01' lle bolts 10. Preferably the side Walls oi. the drum portion are llured reand project through suitable openings 7 ll: 19 formed in the sides ofthe drum. A

(rank or lever 20 is secured to one of said trunnions wherehy the valvemay be raised 1 and towered and a helical pring 21 is sei cured to theother trunnion so as to normally hold the valve in position to close thehypass.

in normal operation, when the exhaust :gases are passing through themufiler, the

valve remains in its closed position resting upon the sent 1?. lVhen,however, it is desired to direet the gases through the bypass, the withthe cireunrferential valve seat 12 which causes the valve to he arrangedat an acute tingle to the axis of the exhaust pipe, thereby directingthe gases of explosion clownward and outward through the hy-pass. Thediameter of the exhaust pipe section land of the inuiiler pipe. seetion3 are approximately the same, but the crossseetionularea oi" the drum isconsiderably larger than the eross-seetional urea. of either of saidpipes, so tin 1 no reeoitingr or eholirig action upon the gases ispossihle. When the gases are heing directed from theexhaust. pipethrough the try-puss they are. directed through an opening which isconstantly increasing in area, since the area ot thenurrowest portion oithe passage, assuming the valve is in its raised positiolnlis greaterthan the crossseetional area. of the exhaust pipe. Theretore, in thisposition of the valve, any choking action upon the gases is impossible.

31y means of this construction I am enaided to provide a inutller cutoutin which somewhat as at ll so as to prov ide a greater 1 cross-sectionalarea in the drum than in the adjacent sections 2 and 25 and the top oisaid drum portion is provided with an inclined semi-circui'n'ferentialvalve seat 1" The hy-pass of the cutout has its axis arranged at anangle to the axis of the exhaust line and is provided at one end with a.horizontal socket or recess 14 transversely positioned with respect tothe ar-zis of the exhaust. pipe, which forms a hearing for thecylindrical end 15 of a. valve 16. The hy-pu. is also provided wi"sniail inwnrdiy projecting ledge or huge I? iio eh ii-strides a seat forthe at: re, the said titiu 1 or the the passage through the exhaust pipeis completely closed, but. in whirh choking ol' the exhaust gases isahsohuely prevented j hy l' iiMm ot' the uniformly enlarged areas of thesueeessive Htt'tlUiiS of the exhaust pussae'e, Furthermore thisconstruction provides means whereby the gases may he delien-tedgradually from their normal path by an int-lined surface instead othaving their motion arrested and their direetiou eoni plete y andsuddenly changed. The cutout;

ran he easily and readily detaehed from the main line oi the exhaustpipe or access may he had to the valve without removing the cutout as aWhole merely by detaching the holts i0 wlrch secure the hy-pass to thedrum,

It ohvious that the cutout may he cur-ed to the exhaust pipe in nunihervalve is raised into engagement.

ways Without using the bolts shown and that the of eiplosion may bedirected from the lay-pass in any desired direction, and that variousother changes Within the skill of the mechanic may be made in theconstruction herein shown Without departing from the spirit of theinvention, provided the means set forth in the following claims heenployed. 10 I claim as my invention l. in a mulller cutout thecombination with the exhaust pipe, of a drum secured in the line of saidpipe, and having a circumferential inclined valve seat formed integraltherewith, a lay-pass detachably secured to said drum and comnnlnicatingtherewith, a valve mounted on said bypass and normally engaging a seatprovided on said bypass, and means for causin said valve to engage withsaid circumferential valve seat and completely close the passage throughthe exhaust pipe.

in a mui'lier cutout the combination with an exhaust pipe, a drumsecured in line thereu 'ith, a bypass secured to said drum and having alarger cross-sectional area than the exhaust pipe, and means adaptedto-he arranged at an angle to the normal path of the gases through saidexhaust pipe. to deflect said gases into the oy-paes through a passagehaving a constantly increasing cross-sectirmal scribed. 3. in a mul'hercutout the combination with the exl'urust pipe, of drum in said exhaus't pipe in line therewith, a hy-pass se-. cured :11. an angle tosaid drunrand having a greater cross-sectional area than said drum, avalve adapted to seat'on the end of the hy-pass and close the same inits lowered position and to seat against the inner Wall of th drum andclose the passage area substantially detherethrough in itsrraisedposition; said valve in its raised position being arranged the exhaustpipe, a circumferential inclined valve seat formed integral with saidcentral section, a lay-pass secured to said central section and having agreater cross-sectional area than said central section, a valve adaptedto engage said valve seat in the central section and completely closethe passagethrough the exhaust pipe, whereby the exhaust gases may bedeflected through a constantly enlarging passage.

5. A mutller cutout comprising a central section adapted to hedetachably secured in an exhaust pipe line and having a circumferentialinternal flange integral; therewith i and gularly arranged with respectto the exhaust pipe line, a bypass pipefdolachahly secured at an angleto said central section and having its end forming a valve seatsymmetrical with respect to said internal flange, a valve in said cutoutadapted to engage said seat and close the by-pass in its loweredposition and to engage said flange and-close thc'exhaust line in itsraiscdpo- 'sition, said valve in its raised position lorun -1ng one wallof acontinuouspassage from the exhaust pipe vtothe'hy-pass oi agradually increasing cross-scctioual area.
